UFO over Stonehenge? Britain releases its last big batch of X-Files

A "discoid shape" is circled in a picture taken at Stonehenge and submitted to the British Ministry of Defense in 2009. The ministry said trying to identify the speck would be an "inappropriate use of defence resources."

Britain's Ministry of Defense finished up its release of almost 60 years' worth of UFO sighting reports on Friday with a bang: a 4,300-page cache of documents that describe strange sights over Stonehenge and Parliament, and lay out the reason why the ministry shut down its UFO desk three and a half years ago.

Thanks in part to the proliferation of camera phones, the number of UFO reports in the U.K. doubled in 2008, to 208 reports for the year, said David Clarke, a UFO historian who reviewed the latest files in a YouTube video. Then, in 2009, the pace of sightings tripled, to a running total of 643 reports by November of that year.

"That really did put a strain on the resources that the MoD had committed to this subject, and really led up to their decision to finally pull the plug on Britain's X-Files, simply because they just didn't have the resources to investigate these sightings, or to look at them in any detail," Clarke said. "So they just tended to be filed away."

That was basically what happened to the Stonehenge sighting: In January 2009, the ministry received several photographs that showed a speck in the sky over the millennia-old monument in Wiltshire. "I didn't see anything in the sky at the time, because I was focusing upon the stones," the witness wrote in an archived email. "Upon uploading them to my computer, though, I spotted the discoid shapes in the background. ... I'm sure you get this kind of thing every day! However, I'm very fond of my UFOs so needed to share them!"

Clarke said many of the mobile-phone snapshots sent in between late 2007 and late 2009, the period covered by Friday's document release, were of such poor quality that it was hard to tell what was going on. The "vast majority" of cases turned out to have down-to-earth explanations, he said. Here's a sampling of the highlights:

A police helicopter crew in Wales reported seeing a cluster of small, rotating objects in the sky in June 2008 — and when word got out about the sighting, the tabloid Sun newspaper heralded it as an "ALIEN ARMY." The ministry concluded that they were Chinese lanterns floating up from a nearby wedding party.

The Sun also trumpeted a story about a damaged wind turbine in North Lincolnshire in January 2009, quoting witnesses who reported that bright spheres of light were flashing in the sky when the turbine broke. "UFO HITS WIND TURBINE," The Sun proclaimed. The ministry declined to investigate, but a journalist at The Guardian said the lights were actually fireworks set off nearby to celebrate her father's 80th birthday. Experts said the turbine probably broke due to an unrelated mechanical failure.

A woman in Dorset reported seeing a "bright white fireball" come through her kitchen window in August 2009. She said the fireball fell into a carrier bag and disappeared in a flash of "blinding white sheet lightning." Clarke said the report matches the classic description of ball lightning, an electrical phenomenon that is not yet fully understood.

A schoolgirl in Altrincham sent the ministry a letter in January 2009, describing a set of small objects that she and her father saw flying over the family's garden. At the bottom of the letter, she drew a picture of an alien waving goodbye from a flying saucer. "Please send a letter telling me the answer. ... I have the right to know," she wrote. The UFO desk reported that the girl was sent a bag of goodies from the Royal Air Force.

"We have now come to the end of this program of release for the UFO files, and it is often said about UFOs that 'the truth is out there,'" Clarke said in the video, which was recorded amid the ministry's filing cabinets. "In my opinion, the truth is actually in here, in these files."
